PLEASE HELP GIVNG MEDALS N FANNING
Four charges are placed at the four corners of a square of side 15 cm. The charges on the upper left and right corners are +3 μC and 6 μC respectively. The charges on the lower left and right corners are 2.4 μC and 9 μC respectively. The net electric force on 9 μC charge is:
18 N, 750 below the positive xaxis
18 N, 750 below the negative x axis
18 N, 750 above the negative x axis
